Estudo e desenvolvimento de aplicativo para a digitalização da manutenção autônoma em uma indústria metalmecânica

Abstract

This article presents the design, development, and implementation of the MA Digital application, a solution aimed at systematizing Autonomous Maintenance (AM) in a metal-mechanic company located in the northwest region of Rio Grande do Sul, Brazil. AM, one of the pillars of Total Productive Maintenance (TPM), aims to engage operators in preserving the operational conditions of equipment, contributing to failure prevention and improved efficiency. The development of this solution was motivated by problems such as inconsistent manual records, lack of data traceability, and increased maintenance costs resulting from the inadequate execution of cleaning, inspection, and basic care routines. The adopted methodology included data analysis from the SAP PM system, application of MFMEA, and Pareto Analysis, which enabled the mapping of the main failure modes and guided the definition of the solution's requirements. The MA Digital application is already operational in two machining centers, allowing standardized routine management, execution control with photographic evidence, full data traceability, and integration with SAP for asset management. The digitalization of AM routines provides greater control, improved data reliability, reduction of recurrent failures, and significant operational gains for the organization.
